A runaway dead star zooming through space at breakneck speeds has left behind a huge trail of matter and antimatter particles. The star is a pulsar called PSR J2030+4415 or J2030 for short; it’s around 20 kilometers (12 miles) in diameter, and it’s speeding through space at a breakneck velocity of around 450 kilometers per … Read more
The Sun is continuing its rowdy behavior, with flares and coronal mass ejections almost every day since mid-January. That means the inevitable has happened: some of those eruptions have blasted in the general direction of Earth, which means we’re in for some solar storms. The Space Weather Prediction Center of the US National Oceanic … Read more
Organs soon run out of energy while they are between donor and recipient, but an electric field could keep them running and improve survival Health 9 March 2022 By Clare Wilson Microscope images showing tissue damage in human donor kidneys without electrical treatment (top left and right) and less damage with treatment (bottom left and … Read more
Fluctuating light from a black hole, observed over 15 years, has revealed more about the way these enigmatic objects feed. First, a structure called a corona forms around the outside of the event horizon. Then, powerful jets of plasma launch from the poles, punching material from the corona out into interstellar space at speeds close … Read more
A new telescope taking on the task of staring at the Sun has delivered incredible new images of solar activity. The US National Science Foundation’s Daniel K. Inouye Solar Telescope commenced science operations for the first time on Wednesday 23 February 2022. It’s the largest solar telescope in the world, and its high-resolution observations of … Read more
The past few weeks or so have been a very busy time for the Sun. Our star has undergone a series of giant eruptions that have sent plasma hurtling through space. Perhaps the most dramatic was a powerful coronal mass ejection and solar flare that erupted from the far side of the Sun on February … Read more
Mars is a parched planet ruled by global dust storms. It’s also a frigid world, where night-time winter temperatures fall to minus 140 C (minus 220 F) at the poles. But it wasn’t always a dry, barren, freezing, inhospitable wasteland. It used to be a warm, wet, almost inviting place, where liquid water flowed across … Read more
Jupiter has finally been observed spitting out X-rays in high-energy wavelengths. Emanating from the giant planet’s permanent auroras, and detected by NASA’s space-based X-ray telescope NuSTAR, the emissions are the most energetic light seen coming from any planet in the Solar System (aside from Earth). The detection could shed light on the most powerful … Read more
While black holes might always be black, they do occasionally emit some intense bursts of light from just outside their event horizon. Previously, what exactly caused these flares had been a mystery to science. That mystery was solved recently by a team of researchers that used a series of supercomputers to model the details of black holes‘ magnetic … Read more
Jupiter’s auroras – the lights that dance around its poles – are the most distinct in our solar system and over a thousand times brighter than Earth’s aurora. Now, a new study confirms that these otherworldly polar lights come from a unique source: space lava. Jupiter‘s moon Io is the most volcanically active world in the solar … Read more
